IF motor有垃圾 then why off 完再on 返部車又郁得返 ne ???
U can try not to turn off and wait for a minute ......then check is the car move again...
If so....then is over heat........u can add a small fan to blow the ESC.
TO check lose wire or not ......also dont turn it off........when the car stop.......try to move the wire .......if this is the wire problem then the car willl move straight away.
